Single Pile in Clay -II

A reinforced ...

Question

A reinforced concrete circular pile of $12 m$ length and $0.6 m$ diameter is embedded in stiff clay which has an undrained unit cohesion of $110 {kN/m}^{2}$ . The adhesion factor is 0.5. The Net ultimate Pullout (Uplift) Load for the pile (in kN, round off to 1 decimal place) is
1244.07

Open in App

Solution

The correct option is A 1244.07
(1244.07)
Pull out load $= α C_{u} . l . p$
$p =$ perimeter
$l =$ length
$= 0.5 \times 110 \times 12 \times π (0.6)$
$= 1244.07 kN$
